Design of Stack Rectangular Dielectric Resonator Antenna for Wireless Application

This paper presents a stack rectangular dielectric resonator antenna for wireless local area network communication systems. The commercial 3D full wave electromagnetic simulation software CST microwave studio is used for this design optimization. The proposed antenna has a small size and low permittivity constant of 2.2 and 2.1 respectively. An impedance bandwidth about 33% from (3.5 to 5 GHz) was achieved making this antenna suitable for wireless application.
